This invention relates to adjustable shelf brackets, and it is a primary object and purpose of the invention to provide a simple, economically produced and strong shelf bracket adjustable vertically at intervals, occupying but little space and so constructed that. articles of merchandise or the containers thereof may be placed underneath the shelf support practically the full length thereof,

' there being no space lost because of diagonally positioned members leading from the outer ends of the shelf support-s downwardly and inwardly at an angle to the ve'rticalmember on which they are attached. The construction for attaining these ends as well as others not at this time specifically stated is fully illustrated in the accompanying drawings, in which,

Fig. l is a perspective view showing an embodiment of a shelf support made inaccord ance with my invention.

Fig. 2 is a vertical section therethrough showing the support as it is being installed or removed from the vertical member.

Fig.3 is a view similar to Fig. 2, the shelf support being shown in operative position.

Fig. 4 is a perspective view showingthe shelf support of my invention.

7 like section 1 from which wings 2 extend outwardly 1n the same vertical plane adapting the same to lie against a vertical wall to which 1 .the member may be attached by means of screws. The channel portion of the member has horizontal-slots 3cut therein'at vertical spaced intervals.

The shelf support is made from a single 5 piece of metal and include-s a horizontal section' which at its outer end is bentback upon itself as indicated at 5, continuing as a section 6 which lies substantially parallel to the lower section l over which it is located, there being, howeverya slightacute angle between the up 9 beingoffset inaplane infront of the parts per and under sides of the sections a and 6 respectively. The section 6 at'its inner free end is CllVlClBCl so as to provide two fingers"? which pass at opposite sides of the channel portion 1 and an upturned lip 8 adapted'to extend through any of the slots 3. i

The inner end 01' the under section 4 is bent i downwardly at right angles to make the vertical leg'9 with adjoining portions 10, the leg 10 so as to'lie against the front side of the channel 1 and oppose the frontsides of the wings 2, respectively; At its lower end the leg 9 has a lip 11 turned rearwardly at right cal member to which it is adjustably attached, U

the lip 8 is passed through one of the slots 3, as shown in Fig. 2, and the shelf support is thenturned in aclockwise direction so as to bring the lip 11 into conjunction with the slot 3 next'below the one through which the lip 8 has been passed. The cam under surface 12 of the lip 11 engages against the lower edge of theslot 3 into which it is to be placed and in order to enter the lip it is necessary to apply suilicient force so that the cam under-, side 12 will ride against and over the under f" edge of the slot- 3 with which. it is engaged. By reason of the slightly angular position of the sections a and 6 with respect to each other, such sections may be sprung toward each othersufiicient distance that the lip 11 may be readily snapped into its slot 3; and the spring stress set up causes the underside 12" of the lip 11 to beartightly against the lower edge of the slot 3 into which the lip 11 extends, thereby retaining the shelf support securely in place, though such support may be readily removed by application of an upward tilting pressure against theunderside of the outer end of the support It is evident that the shelf support de-" scribed occupies a horizontal position and shelves may be carried by rest-ingthe same against the upper sides of the section 6. The

right angle lo-cation of the two parts 4 and 9 with respectto eachother makesv it possible to fill the entire space with books, articles of merchandise or the like carried on the shelves. The snap engagement of the shelf supports with the vertical member on which they are mounted insures against accidental displacement of the supports.

In Fig. 5 the shelf support is shown in a somewhat different form. Instead of the leg 9 and adjoining portions 10 being turned downwardly from the under section 5 the leg 9a with adjacent portions 10a are turned upwardly from the inner end of the upper section 6 and the lip 8a is formed at the upper end of the leg 9a. Also the lip 11a is formed at one end of and in the same plane with the section 4 having an undercam surface 12a similar in all respects to the cam surface 12 on the lip 11 previously described.

This shelf support may be applied to the vertical channel member in exactly the same way as the first structure and has all of the advantages thereof and is frictionally held on the vertical support in the same manner.

These devices have proved very practical and satisfactory in service. The invention is defined in the appended claims and is to be considered con'iprehensive of all forms of structures coming within their scope.

I claim:

1. In combination with a vertical sheet metal channel member having Wings extending outwardly from the rear edges of the flanges, a shelf supporting member comprising a substantially horizontal section, a second section bent back underneath the first section and slightly spaced therefrom, a third section extending downwardly from the inner end of the second section, said third section having offset portions adapted to oppose the outwardly extending Wings of the channel member, a lip extending upwardly from the inner end of the first section and a second lip extending substantially horizontal at right angles to and at the lower end of the third section, substantially as and for the purposes described.

2. A channel member having a shelf supporting member as recited in claim 1 but also characterized by the fact that the aforesaid first mentioned horizontal section has fingers extending from the inner end thereof, said fingers being adapted to contact with the wings on the channel member.

3. In combination with a Vertical sheet metal channel member having a plurality of spaced apart slots therein, a shelf supporting member comprising a substantially horizontal section, a second section bent back underneath the first section and slightly spaced therefrom, a third section extending downwardly from the inner end of the second section, said third section having integral portions extending laterally therefrom, said portions being adapted to contact the flanges of the said sheet metal channel for the purpose JOSEPH J.
